Hi Henk,
you have posted here in the PSR-3000/1500 category. But these models do NOT support Expansion Voices that are based on new Samples.
Which keyboard model do you have?
There is a Pack with some "Vox Continental Organ" Expansion Voices for YEM compatible models (.
ppf format) on Peter Schips website cms-sounddesign.de:
http://cms-sounddesign.de/page104.htmlI recently also saw such voices for T3/T4 (.
uvn format) on the web.
There also thousands of so called "User Voices" (.
vce) on the web which contain "vox" in their file names. THESE Voices CAN be used on PSR-3000/1500, BUT most of these voices are only "Choir" voices ("Vox" means "Vocal" here) or they are Pipe Organ voices, such as "VoxTibia".
You can find "User Voices" here:
